Answer:
Explanation:
Heat transfer occurs by three main mechanisms: conduction, where rigorously vibrating molecules transfer their energy to other molecules with lower energy; convection, in which the bulk movement of a fluid causes currents and eddies that promote mixing and the distribution of thermal energy
Answer:
The correct answer is B: reaction A is endothermic and reaction B is exothermic.
Explanation:
A: 6CO2(g) + 6H2O(l) + sunlight → C6H12O6(aq) + 6O2(g): is the photosynthesis reaction. Photosynthesis is an endothermic reaction, therefore it needs energy (sunlight) to take place.
B: 2H2(g) + O2(g) → 2H2O(g) + energy: is the formation of water. It is an exothermic reaction which releases energy as a result of the reaction.
So, the answer is option (B): Reaction A is Endothermic and Reaction B is Exothermic.
Answer:
MnO3 radical anion. Formula: MnO3- Molecular weight: 102.9368.
Oil<span> and </span>water<span> are two liquids that are </span>immiscible<span>, meaning they will not mix together. Liquids tend to be </span>immiscible<span> when the force of attraction between the molecules of the same liquid is greater than the force of attraction between the two different liquids.</span>
Answer:
Tortillas generally last for a week after their "best by" date on the counter and about a month if placed in the fridge. But it sometimes depends on how they are stored
